Federal Register Notice: Reopening of Comment Period and Notice of Data Availability for Amendments to Hazardous Waste Testing and Monitoring Regulations

On January 23, 1989, the Agency proposed to amend its hazardous waste testing and monitoring regulations under Subtitle C of Resource Conservation and Recovery Act (RCRA) by:

(1) Incorporating the Third Edition of "Test Methods for Evaluating Solid Waste, Physical/Chemical Methods," (SW-846) into the RCRA regulations;
(2) updating SW--846 with additional methods and information; and
(3) mandating minimum Quality Control (QC) procedures for all RCRA testing.

The public comment period for this proposal was reopened for the purpose of receiving comments, with supporting documentation, on new options and the deletion of appendices III and X.
